Python — Least Frequent Character in String
This program helps us to find the frequency of minimum occurring characters in a python string. This is quite an important utility nowadays and knowledge of it is always useful.
Method 1: Naive method + min()
In this method, we simply iterate through the string and form a key in a dictionary of newly occurred elements or if the element already occurs, we increase its value by 1. We find a minimum occurring character by using min() on values.
Output :
Method 2: Using collections.Counter() + min()
The most suggested method that could be used to find all occurrences is this method, this actually gets all element frequency and could also be used to print single element frequency if required. We find a minimum occurring character by using min() on values.
